SAN DIEGO: A school bus with no children on board ran into a house near Guymon Street and Euclid Avenue in Emerald Hills yesterday afternoon, San Diego police said.

The bus driver may have had a seizure about the time of the accident, which was reported about 4 p.m., police Detective Gary Hassen said. She was taken to a hospital for evaluation, said San Diego Fire-Rescue Department spokesman Maurice Luque.

The bus initially crashed into the rear of a van at a stop sign, then veered into the house, Luque said. The van's occupants, a 44-year-old woman and her 9-year-old son, were taken to a hospital for evaluation, he said.

Officers started an investigation and were trying to determine the amount of damage to the home, which Luque said appeared to have sustained extensive damage to the front.

The home's residents, a 38-year-old man and his 70-year-old mother, were not home at the time, Luque said.
